Hello all. This is my first post here so first I would like to say thanks in advance for the future support!! I have a Sprint Photon 4G and when the 4G is tirned on, it works for the first web page and while reading the page it looks to "Go to sleep". It has all the zzz's and has no connectivity. It seems to me like if I lost 4G service, it would usually revert back to 3G but it does not. I have to turn 4G off and back on and it does it again. I have updated the PRL and the Profile and still no fix. I googled it but didnt see any fix but looks to be a common problem. PLEASE HELP ME!!! THANKS IN ADVANCE
